The Lowdown
Alright, Rusty here, and I’m looking straight at the forecast for Jaconé. Let’s break it down.
The coming week-and-a-bit has a few really promising windows, but you’ll have to be patient and pick your sessions. The water is sitting at 73°F, which is about normal for this time of year – nothing weird going on there.
The first real standout is Friday the 11th. We’ve got a solid groundswell from the south, with a very long period of 14 seconds pushing in around 4ft. The combined energy is strong at 1034, and the morning brings a clean offshore breeze from the NE at 15 km/h. This is prime for the experienced crew – the wave quality will be excellent, with that long-period energy wrapping in nicely. The only catch is that long period can make the waves stand up a bit fast, but it’s a good setup here.
The next one to circle is Monday the 14th. The morning is a bit brisk with a moderate offshore wind from the ENE at 25 km/h, holding up 5ft of S swell (moderate energy at 649). The afternoon cleans up with a cross-offshore breeze, making for very good conditions. It’s not the biggest, but it’s clean and consistent.
Looking further out, Friday the 18th also has some real potential. Another clean morning with a gentle offshore NE wind, pushing 5ft of S swell (energy at 542). The afternoon goes glassy – zero wind – with still decent 4ft waves. That’s a beautiful window for a long session.
Saturday the 19th has some size in the morning at 6ft from the ENE, but the period is short at 7 seconds. It’s clean, but the short period means it’ll be a bit bouncy and less powerful. Not a total write-off, but not the top pick.
There are a lot of so-so days in between with onshore winds or small, weak swell. The 9th and 10th are pretty marginal. The second week starts to fade noticeably after the 20th, with much smaller surf and poor conditions through the 24th. The energy drops right off.
So, for the best bet: Friday the 11th morning is the clear winner – that long-period groundswell with offshore wind is a proper highlight. Monday 14th afternoon and Friday 18th are your backup standouts. Just remember, the further out we get, the less certain it is, but it looks promising.
This is Rusty, signing off.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
